Several methods were used to measure the spatial distribution patterns for eggs and larva of Atysa marginata cinnamomi Chen in Fujian province. The results showed that the eggs and larva obeyed Neyman distribution, and which basic component of spatial distribution is loose colony, the aggregated distribution of larva would turn into uniform distribution as a result of diffusing continually. The optimal sampling number was calculated by lwao's method, and the sequential analysis is also analysed.
